NCT ID: NCT05986682

Last Updated: 2025-02-03

Results Overview

Duration of Treatment Duration calculated from first Blenrep dose to either treatment discontinuation (for subjects who discontinued treatment prior to study end date) or last dose (for subjects who were continuing treatment as of study end date). Descriptive statistics consisting of the median (with interquartile range) was used to summarize duration across participants.

Recruitment status

COMPLETED

Participant Flow

This was a single-site, retrospective, observational study examining longitudinal care patterns for belantamab mafodotin among relapsed and/or refractory multiple myeloma (RRMM) patients seen at Duke Cancer Institute (DCI).

57 Duke patients were identified with RRMM who began treatment with Blenrep between Aug 5, 2020 and Nov 22, 2022. 25 patients were excluded (9 concurrently receiving other therapies, 8 being followed by a local oncologist or without Blenrep Risk Evaluation and Mitigation Strategies \[REMS\] documentation, 5 with \<1 mo. of follow-up, and 3 receiving Blenrep as part of an expanded access pathway). Of the 32 remaining patients, 30 patients were randomly selected for chart abstraction.

Response categorized using modified IMWG 2016 criteria. Urine testing was not routinely done; only serum M-protein levels were used when determining response. Complete Response(CR)= negative immunofixation on the serum + absence of any soft tissue plasmacytomas + \<5% plasma cells in bone marrow aspirates. Very Good Partial Response(VGPR) = serum detectable by immunofixation but not on electrophoresis or ≥90% reduction in serum M-protein. Partial Response(PR) = ≥50% reduction of serum M-protein. If the serum is unmeasurable, a \> 50% decrease in the difference between involved and uninvolved FLC levels is required. Stable Disease (SD) = not meeting criteria for CR, VGPR, PR, or progressive disease. Progressive Disease (PD) = \>25% increase from lowest response value in serum M-protein (the absolute increase must be \>0.5 g/dL), or definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas.

Distress is measured on a scale of 0-10 on the National Comprehensive Cancer Network Distress Thermometer (NCCN DT). A score of 0 represents no distress, and a score of 10 represents worst possible distress. Actionable distress is defined as a NCCN DT score of 4 or higher, and is aligned with the medical practice guidelines for management of distress in cancer patients.The median (min, max) distress score across patients is reported.

Sources of distress will be assessed using the NCCN DT Problem List by examining the percentage of visits where types of problems are reported. There are five categories of distress from which patients can report problems (practical, family, emotional, physical and other problems). The categories of problems are reported as a number and % of the total number of visits where problem lists are reported.

To the extent that they are available, HCRU \[i.e., radiation therapy, transfusions (red blood cells or platelets), inpatient admissions, treatment-related outpatient visits, emergency department visits, palliative care outpatient visits\] that occurred during BLENREP treatment will be summarized by the percentage and frequency distribution of patients with any occurrence of the respective outcome.

Population: The 30 patients in the study reported specific symptoms a total of 192 times at clinic visits. The analysis population is the 192 symptoms reported.

Study procedures included recording ocular symptoms reported by patients documented in the clinic notes. These were categorized into blurry vision, dry eyes, photophobia and other symptoms (including foreign-body sensation, "grittiness", "itch/scratchiness", irritation, and tearing). This Data table reports the total number of Ocular Symptoms reported by patients, along with counts and percentage by type of symptom.

POST_HOC outcome

Timeframe: Between baseline and earliest of end of BLENREP treatment, death, lost to contact or end of study timeframe, up to 40 months.

Population: The 30 patients in the study experienced ocular toxicity (corneal events) a total of 323 times as reported during clinic visits. The analysis population is the 323 events reported.

Ocular toxicity as measured by corneal events per the Keratopathy Visual Acuity scale, and graded using belantamab mafodotin REMS \[Risk Evaluation and Mitigation Strategies\] guidelines. Corneal examination changes from baseline are categorized as normal or grade 1, 2, 3, or 4 and are based on the worst overall finding. Normal: Cornea clear/No change from baseline. Grade 1: Mild superficial keratopathy with or without symptoms. Grade 2: Moderate superficial keratopathy. Grade 3: Severe superficial keratopathy. Moderate/Severe keratopathy could be with or without patchy microcyst-like deposits, sub-epithelial haze (peripheral), or a new peripheral stromal opacity. Grade 4: Corneal epithelial defect (such as corneal ulcer). The Data table reports the total number of corneal events experienced, along with counts and percentage by grade of event.

Timeframe: Between baseline and earliest of end of BLENREP treatment, death, lost to contact or end of study timeframe, up to 40 months.

Clinically Meaningful Event is defined as an event that is grade \>= 2 for which BLENREP administration is halted until the event resolves to grade \<= 1. Time to resolution is calculated for events that resolved. Unresolved events are those that had not returned to grade \<=1 at last contact due to either end of study or lost to ophthalmologic follow-up. There were 64 resolved events for Corneal Events that were analyzed

POST_HOC outcome

Timeframe: Between baseline and earliest of end of BLENREP treatment, death, lost to contact or end of study timeframe, up to 40 months.

Population: The 30 patients in the study experienced ocular toxicity (changes to BVCA) a total of 244 times as reported during clinic visits. The analysis population is the 244 BVCA changes reported.

Ocular toxicity as measured by changes to BVCA as measured per the Keratopathy Visual Acuity scale, and graded using belantamab mafodotin REMS \[Risk Evaluation and Mitigation Strategies\] guidelines. BVCA changes from baseline are categorized as normal or grade 1, 2, 3, or 4 and are based on the worst overall finding. Normal: No decline from baseline on Snellen Visual Acuity. Grade 1: Decline from baseline of 1 line on Snellen Visual Acuity. Grade 2: Decline from baseline of 2 or 3 lines on Snellen Visual Acuity, and not worse than 20/200. Grade 3: Decline from baseline of more than 3 lines on Snellen Visual Acuity, and not worse than 20/200. Grade 4: Snellen Visual Acuity worse than 20/200. The Data table reports the total number of BVCA changes experienced, along with counts and percentage by grade of change.
